Since the Droid RAZR has a non-removable battery, the RAZR MAXX is akin to a permanent extended battery.

It would have been a little more fair to consumers to introduce both the RAZR and RAZR MAXX at the same time, but now that they're both announced, it's a sensible lineup.

There really aren't any other differences; the features are the same.

The RAZR MAXX comes with 32 GB of built-in memory, just like the original Droid RAZR. But now Verizon also offers a version of the Droid RAZR with just 16GB. They also offer that 16 GB version in three colors: gray, white, and now purple.
